A Survey of VHF Man-made Noise in the Metropolitan City Area of New Delhi

Abstract

Multiple sets of man-made radio noise data are reported for a number of locations in the metropolitan city area of New Delhi. These are examined to assess the frequency, distance and diurnal characteristics of the composite city noise for urban locations. The measurement was restricted in the frequency band of 50-100 MHz to observe the impact of noise on VHF land-mobile and TV broadcasting services. The incidental noise environment to be experienced by these services at different busy activity zones of the city is observed to have a contrasting spectral pattern.
